HARVEY L. BECK, OF CID, NORTH CAROLINA.

SPLIT-MACHINE.

SPECIFICATION forming part of Letters Patent No. 689,277, dated December 17, 1901.

Application filed March 5,1901. Serial No. 49,740. (No model.)

To all w/wm, it may concern:

Be it known that I, HARVEY L. Back, a citizen of the United States, residing at Cid, in the county of Davidson and State of North Carolina, have invented new and useful Improvements in Split-Machines, of which the following is a specification.

My invention relates to split-machines for the purpose of cutting or makingsplits for use in chair-making or the like, the object thereof being to so construct the same that by the simple manipulation of a wheel upon or around which the timber is secured the wood is brought into contact with anadjustable bit or plane secured in an adjustable stock and the splits severed from the timber.

In the drawings forming a part of this specification, and in which like symbols of reference represent corresponding parts in the several views, Figure l is a longitudinal sectional view of the machine; Fig. 2, a longitudinal view with a modification of the polishing-rolls. Fig. 3 is a transverse view on line 2 2 of Fig. 2. Fig. 4. is a side view of the polishing-rolls and the band for operating the same. Fig. 5 is a plan View of the same. Fig. 6 is a modification of the polishing-rolls, and Fig. 7 is a View of the bit or plane.

The device is supported in a frame consisting of four posts 2,'secured at their ends by cross-pieces 3 and on the sides by side bars 4. Within this frame is supported the wheel 5 in suitable bearings on the side railings 4, and onoue side of the axle there is a crank 6 for the purpose of operating the machine. This crank may of course be substituted by any other driving power desired.

8 is a slot within which the piece of timber 9 is inserted and held fast by aclamp l1, and 9 is a second slot within which the other end of the timber is placed after being bent, as hereinafter described, and secured and tightened by a draw-clamp 19.

12 is a lever for forcing the free end of the timber into the slot 9 after it has been bent around the wheel 5 by the bending-rollers 10, which are set in boxes adjustable on springs and with which the wood contacts in the revolution of the wheel. It is to be understood that the adjustable rollers 10 and 23 may be increased in number as necessary.

13 is a bit or plane supported in bit-carrying arm 14, its purpose being to sever the splits longitudinally from the piece of timber after the same has been bent.

13 is a crank-arm supported in the polishing-roll frame and having a pivotal connection with the plane, so as to elevate and throw the same out of operation when it is desired to operate the bending mechanism.

13 is a spring for holding the bit in its operative position with relation to the timber being split.

20 is a pulley, and 21 a band connected with said pulley and to a pulley on the rolls 15, its purpose being to impart motion to said rolls. Motion is imparted by a band 22 from rolls 15 to a serrated roll 18, which works in conjunction with a plane surface 18, to a serrated roll 19,.which works in conjunction with a plane surface 19 In the modification shown in Fig. 6 the split is fed from rolls 15 between rolls l6 and 16' to rolls 17 and 17, rolls l6 and 17 running at a greater rate of speed than the accompanying rolls for the purpose of polishing the split on that side and, furthermore, being serrated or having abrading material thereon to operate upon the split.

23 represents small rollers which work in conjunction with bending-rollers 10, said rollers 23 being journaled on spring metal, so as to haveaspringy action,or they maybe housed in spring-boxes, if desired,-the object being to make the same adjustable, so as to conform to the material operated upon.

The operation of the device is as follows:

The piece of timber is placed in the slot 8 and secured by the clamp 11. The wheel is then turned from right to left until the slot 8 passes all of the bending-rollers and the timber is bent against the wheel 5, the bit in the meantime being elevated from its working position by the crank 13. When the timber comes over the slot 9, the lever 12 is operated and the end of the timber forced into said slot and secured by clamp 19, said clamp having clamping-jaws and a turnbuckle to operate upon the timber. The bit is then released, so as to assume its operative position, the wheel turned until the timber is brought into contact with the bit, and the splits severed from the same, the bit and bit-carrying arm being adjustable by means of the spring controlling the'bit and the hinge supporting the v separated that it is an easy matter for the bit to sever the same, and, furthermore, the split thus secured is very much more desirable than those that are not formed in accordance with the grain or vein of the wood, for the reason that they do not splinter, crack, or split, as is common in material of this kind.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination with a wheel, means for securing and bending the wood thereon, and means for stripping portions from the wood when bent.

2. In a device of the character described, the combination with a wheel, means for securing the material thereon, means for bending it around said wheel, an adjustable bit to act upon the material when bent, and rolls to receive and polish the material after it is severed.

3. In a device of the character described,

the combination with a wheel, of adjustable bending-rollers adapted to operate in conjunction with the same, means for securing the material around the wheel, adjustable bending-rollers adapted to operate in conjunction with the main bending-rollers, an adjustable bit to strip the material as the wheel is revolved, and polishing-rolls to receive and polish the material after it is severed.

4. In a device of the character described, the combination with a wheel, of adjustable bending-rollers adapted to operate in conjunction with the same, means for securing the material around the wheel, adjustable bending-rollers adapted to operate in conjunction with the main bending-rollers,which bending process breaks up the cohesive attractions between the atoms of the wood, means for separating strips from the material as the wheel is revolved, and polishing-rolls to receive and polish the material after it is severed.

In testimony whereof I afiix my signature in presence of two witnesses.
